Narrative
On 5/17/2018 @7:55 a 3rd party operator contacted empco of a possible release at empco's shintech meter site. Empco dispatched technicians and at approximately 08:24 discovered a small ice ball forming on the packing gland housing of an orifice meter. The system was shut-in, and at approximately 12:11 p.M. The system was returned to service following the tightening of a loose packing gland fitting. Empco estimates that approximately 17.11 gallons (0.40 bbls) of ethylene was released. The spill volume was conservatively estimated assuming a continuous release rate, without accounting for any potential flow reduction rate due to observed ice-ball formation, and assumptions regarding the release start time based upon a post-incident identification of local intermittent gas detector indications beginning at approximately 1:01 am and again at approximately 4:27 am.
